Preparation method of structural wheat straw gypsum composite material
The invention discloses a preparation method of a structural wheat straw gypsum composite material, discloses a structural wheat straw gypsum composite material and a preparation method thereof, and belongs to the field of buildings. The preparation method comprises the following steps: mixing wheat straws and kenaf fibers, then mixing with gypsum and magnesite gel, paving, pressurizing and curing. On the premise that a large mixing amount of wheat straw is used as a reinforcing phase and the fire resistance of the composite material is ensured, the mechanical property of the reinforcing phase is improved by mixing a small mixing amount of kenaf with high strength and wheat straw wood shavings, and the mechanical property of the composite material is favorably improved; a magnesite gel fine structure is constructed in a gypsum crystal phase coarse structure, so that the mechanical property of a base phase is improved, the mechanical property of the composite material is further improved, and the indexes of structural plates for buildings are met.
本发明公开了一种结构用麦秸石膏复合材料制备方法，本发明公开了结构用麦秸石膏复合材料及其制备方法，属于建筑领域。它包括麦秸和洋麻纤维混合、再与石膏和菱镁凝胶混合，经铺装、加压和养护。本发明在大掺量麦秸为增强相、保证复合材料抗火性能的前提下，采用小掺量具有高强特性的洋麻与麦秸刨花的混合，提高了增强相的力学性能，有利于复合材料力学性能的提升；通过在石膏晶相粗结构中构筑菱镁凝胶细结构，改善了基相力学性能，进一步提高了复合材料的力学性能，符合建筑用结构板材指标。
